That's about what they go for. Does it have Posi?
Unless you can get the driveshaft out of the GN too, you'll have to have yours shortened 1 inch.

Take it to a drivetrain shop and have them cut and balance it.
Around here we've got a place called Proven Force that does stuff like that. You'll have to look into what's in your area.
I had my driveshaft shortened and balanced for $90.

If you're serious at all about racing it, now would be a good time to install a driveshaft safety loop.

Here's a pic of the loop in my 87 monte SS...(rear isnt swapped in yet)
That's a good price for that rear end. They go for $1200 to $1500 in my area. I lucked out and got mine for 600 with 3:73's in it and por-15 treated.

Thanks for posting that, man! I will definitely be ordering one of those when I do my 8.5 swap.
